The player has seven types of characters to choose from: warrior, wizard, elf, magic gladiator, dark lord,summoner and rage fighter. The main characteristics of the characters are strength, agility, life, and mana (magic power).
Dark Knight has great strength, powerful weapons, and is an expert in destroying the monsters that inhabit the muonline continent.
Wizard (Dark Wizard) is slightly weaker than the Warrior at the beginning of the game, but his spells deal damage to several monsters at once, which significantly speeds up leveling—an undeniable advantage in the world of MuOnline.
Elf (Fairy Elf) can be upgraded in one of two directions: agility or energy. An Elf with upgraded agility can gain levels on her own, while an Elf with upgraded energy can heal and strengthen other characters, making her indispensable in group battles.
Summoner controls elements and summons magical creatures to aid her. She also has the unique ability to drain the life force of her enemies. Some consider her the female incarnation of the magic gladiator.
Magic Gladiator combines almost all the strengths of a mage and a warrior. However, he cannot wear a helmet, which lowers his armor protection. This disadvantage is compensated by his lethal attacking power.
Dark Lord commands magical animals that grow and gain experience alongside their master. Rage Fighter is a specialist in close combat, introduced in Season 6 of MU Online. He can be created after reaching level 200 with any character.
Rage Fighter Forgotten empire “Kalutan”. The Rage Fighter is a remnant and descendant of Kalutal roayal knight. They are specialized for charge attack based on their physical advantage and use special buffs learned from Kalutan royal knight.
